Do you want to be able to do green-screen video productions? Here are some helpful techniques that could get you on the right track. I will already assume that you do have the camera, lights and green-screen. The guide below is about on how to fix them properly. First thing, the color that works well with cameras is the chroma green. Have you already heard about 4:2:2 color space? Also RGB? This is what it really means, most color information is stored in the Green space of the color channel (G) on your digital camera. So make sure that green-screen is the right color. 1. First Thing: Lights Lights are THE MOST IMPORTANT aspect of creating quality separation of your subject from the green-screen - and ultimately - a good key. what I mean with key is that when you bring the motion picture into your editing software, your subject separates well from the background. This is what separates the pros from the amateur. You could have the top of the line tools and crews, but if have not been not successful with this separation, all the best efforts would be useless. . No down to the details. 2. Use a back light When I say this, I mean a light that illuminates the back of your subject. Sometimes this light is higher in the air, sometimes lower (I recommend about 20% higher than your subject) but it is ALWAYS pointing at the back of your subject (in between your subject and the green-screen). Put that light on a 45 degree angle. Getting one light per side (same angle, same height) is ideal. So what does this do? Well it creates a subtle white "halo" around the edges of your subject. Like a small white or illuminated edge, it's going to dramatically affect the quality of your key. 3. Light for the green-screen There should be an even covering of light into the green screen. Ideally, there should be no brighter parts, no wrinkles, no shadows, even and green. 4. Choosing Lights Ways of lighting that green-screen? A light on either side. Overheads and floor lights. This creates a Cyc lighting that brings up an even light from the floor going up. This lights could be rented at a gear rental shop in your local area. Personally, I use a 4-bank KinoFlo on either side of the screen. It actually depends on how much you expect the object to move. Article Source: http://www.ArticleBlast.com |
